FIG. 1 shows a schematic structural diagram of a lighting system according to an embodiment of the present invention. In conjunction with FIGS. 2 and 3, the lighting system 1 comprises an emergency power supply assembly 10 and lighting assembly 20.

Referring to FIG. 2, the emergency power supply assembly 10 includes an emergency power supply 11, a test switch 13 and a splitter 12. Wherein, the emergency power supply 11 may be a battery or a battery assembly. It is understood that the battery or battery assembly may be any suitable type of battery for providing emergency power. In an embodiment of the present invention, a power source sold by IOTA Corporation is selected as the emergency power source 11.

The test switch 13 is electrically connected to the emergency power supply 11 through a flexible cable 30 for testing whether the emergency power supply 11 is in a normal working state. According to an embodiment of the present invention, the test switch 13 is a push switch, the push switch is further electrically connected to a test signal indicating device (not shown), when the push switch is pressed down, the test signal indicating device emits a color change, such as an optical signal, and indicates through the optical signal whether the emergency power source 11 is in a normal working state. It is to be understood that an audible signal may also be emitted to indicate whether the emergency power supply 11 can provide emergency power as normal by the level of its decibels.

The splitter 12 may be a housing 120 having an accommodating space which can be opened and closed, which may provide a first connecting portion 121, a second connecting portion 122 and a third connecting portion 123. The first connecting portion 121 is for connecting to the lighting assembly 20, the second connecting portion 122 is for electrically connecting to the emergency power source 11 through a flexible second cable 32, and the third connecting portion 123 is for connecting to an external power source (not shown).

The first connecting portion 121 may be a connecting hole (not shown) formed on the housing 120 of the splitter 12. The first cable 31, covering each of the functional wires, may connect the respective functional wires to the housing 120 of the splitter 12. According to an embodiment of the present invention, an end portion (not shown) of the first cable 31 connected to the connecting hole has a thread (not shown) and a limiting member (not shown) adjacent to the thread. It can be understood that the threaded end of the first cable 31 extends into the housing 120 through the connecting hole. However, the limiting member prevents the first cable 31 from extending into the housing via the connecting hole 120, and is further matched with the thread of the end of the first cable 31 by a matched thread fixing ring (not shown). That is, from inside the housing 120 of the wire distributor 12 toward the outside of the housing 120, the thread fixing ring is rotated along the thread track of the end of the first cable 31 to be in close contact with the inner wall of the housing 120 so that the first cable 31 is fixedly connected to the splitter 12.

The second connecting portion 122 may be another connecting hole (not shown) formed on the housing 120 of the splitter 12, and a second cable 32 covering each functional wire electrically connected to the emergency power source 11. The respective functional wires are fed into the housing of the splitter 12 via the other connection hole.

The various functional wires are fed into the housing 120 of the splitter 12. It can be understood that the third cable 33 and the housing 120 of the splitter 12 can be fixedly connected to the first cable 31, the second cable 32 and the housing 120 of the splitter 12 in the same manner. In some embodiments, the fixed connection method may include the third cable 33 being fixedly connected to an additional connection hole by using an additional engagement mechanism (not shown). The engaging mechanism forms a passage (not shown) at the further connecting hole such that the third cable 33 can only extend into the housing 120 unidirectionally, when reaching a defined distance, the engaging mechanism will prevent the third cable 33 from continuing to protrude into the housing 120. In this case, the third cable 33 is also restricted from moving outside the housing 120 and the third cable 33 is fixedly connected to the additional connecting hole.

Within the housing 120 of the splitter 12, the respective functional wires respectively covered by the first cable 31, the second cable 32, and the third cable 33, will be connected one by one to form a circuit for a predetermined function. As a result, by using the splitter 12, on-site pre-wiring can be avoided.

The driving connecting portion 221 may be a connecting hole (not shown) formed on the case 220. The driving cable 34 covering each of the function wires may be used to feed the electric wires into the case 220 via the connecting through hole, which is electrically connected to the light-emitting unit so as to form a driving control for the light-emitting unit in the power-on state. It can be understood that the driving cable 34 and the case 220 can be fixedly connected to the first cable 31, the second cable 32, the third cable 33, and the housing 120 of the splitter 12 in the same manner.

The mounting base 23 is used for mounting the light-emitting unit, which is also used for supporting the case 220. Further, a reserved hole 231 is formed in the mounting base 23 for the test switch 13 of the emergency power source to pass through. According to a specific embodiment of the present invention, the test switch 13 and the reserved hole 231 are fixedly connected by a screw thread, the push switch and the light emitting unit of the test switch 13 are both located on the same use surface of the mounting base 23. The use surface is the surface of the lighting assembly 20 viewable by the user during installation and use.
